Blog 10: EQ


1. Review this. Confirm by stating "I reviewed the rule of three for writing an EQ."

Essential Question
Once a topic is chosen, the student will develop a working essential question. The purpose of the working essential question is to help the student build a strong foundation of research which will allow him or her to create an essential question that encourages depth and rigor in the chosen topic. An essential question must:

Provide a framework for studies (It calls for breadth and depth of research, Is not a yes/no question)
Take a stance (It allows you to argue some point, Cannot be a recitation of facts or a list)
Format (It is specific, The wording makes sense)

I reviewed the rule of three for writing an EQ. 

2. Review the following EQs and

Tell us if each meets the rule of three.
Tell why they do or don't.

a. What is the most important factor in healthy weight loss?
  • Yes because it requires thorough research to determine the most important factor, and that factor is not the same for everyone, so it requires you to take a stance. Its wording also is very specific, not just being healthy or losing weight but losing weight healthily. 

b. What is most important to securing a conviction in a criminal investigation?
  • No because it is asking for what is the most important which means it will most likely just be facts about most used information in securing a conviction.
c. What is most important in creating a hairstyle that best satisfies a customer?
  • No because, like the last, it wants to what is the most important in creating a hairstyle which is not very clear, the most important what? It also implies an easily obtainable answer, that probably can't take a stance with.
d. How can an anesthesiologist best treat chronic pain?
  • No because this is something that does not really allow you to take a stance, it either is or is not the best way to treat the pain. 

3. Based on your review of the rule of 3 and your experience with assessing four EQs, please write another draft EQ for your senior project. The senior team will be meeting with students shortly for EQ revision and approval; you are expected to bring your research notebook to that meeting with your EQ draft written inside in pencil.

  • How can one best change the basic design of an aircraft to improve fuel-efficiency by reducing drag and weight?

Blog 9: Lesson 1 Reflection



1. Positive Statement

a. What are you most proud of in your Lesson 1 Presentation and why?

I am pretty proud of my lessons in aerodynamics because I thought I did a fairly good job at explaining it in basic terms.

2. Questions to Consider

a. What assessment would you give yourself on your Lesson 1 Presentation (self-assessment)?

P

b. Explain why you deserve that grade using evidence from the Lesson 1 component contract.


I feel like I executed my lesson pretty well and met all the requirements outlined in the rubric.

3. What worked for you in your Lesson 1?


What worked for me during my first lesson was my hook activity because I told everyone to make a paper airplane... oh excuse me... a paper "glider" from a simple piece of paper. I think it was entertaining to the audience.

4. (What didn't work) If you had a time machine, what would you have done differently to improve your Lesson 1?

If i had a time machine I would practice my presentation more before hand so I knew at least a decent idea of what I was going to say and how long it was going to take.

October Additional Blog Post

This month for my senior project I have begun to work on my independent component and began the search for a new mentor. 

     For my independent component, I began researching different types of airfoils I could choose for the design of the craft. An airfoil is the shape of the wing from the side of it and has a huge impact on the lift and aerodynamics of the wings.(Example of the schematic of one shown below)     I encountered many different varieties to choose from, all of which had different affects on the planes turning, or roll. Since I did not want to get fancy, I decided on an airfoil known as NACA(National Advisory Committee for Aerodynamics) 0015. The NACA airfoils are followed by 4 numbers. The first two decide whether or not there is any camber on the airfoil, like the one above. To make it easier and simpler on myself, I chose one without camber. Camber, by the way, is the symmetry between the top and bottom half of the airfoil. Since NACA 0015 has none, it is considered symmetrical. After second pair of numbers determines the width of the airfoil at the thickest point. Since the number is 15, that means at the max point, the airfoil is 15% of the chord length thick. (NACA 0015 Pictured below)

     I decided on NACA 0015 because it was a simple one to construct and provided nothing special, but would allow the craft a fair amount of maneuverability. After deciding on this, I now must determine how long I want or need my chord length so I can begin to construct the most basic airfoil and continue from there.

Blog 8: Research and Working EQ

1. What is your working EQ? 

What is the best way to alter the structure of an aircraft to reduce drag and improve fuel-efficiency?

2. What is a possible answer to your working EQ? 

By implementing blended wing body, an aircraft is able to produce lift across the whole structure reducing drag and weight factors allowing for improved fuel-efficiency.


3. What is the most important source you have used that has helped you come up with an answer to your working EQ?

My most important source so far has been "Fundamentals of Aerodynamics" from the Naval Aviations School Command because it introduced me to several physics concepts that affect an aircraft's flight performance and allowed me to better understand why structural changes, like they blended wing body, affect the craft's fuel efficiency.

4. Who is your mentor and how does what you are doing relate to your working EQ?

I currently do not have a mentor anymore, but am looking hard to find a new one.

Blog 7: Independent Component 1 Approval

1. For my 30 hours, I plan to design, construct and possibly fly a remote control airplane. By doing this, I will learn the basics of aircraft design, as well as, put into practice some of the ideas and concepts I have been learning about in my research. It will also allow me to get more hands on with my project and provide me with a, hopefully, fun way to better understand my topic. Ultimately, to complete it, I will continue to research and get insight into basic aircraft design.

2. To provide proof/evidence of my 30 hours of work, I will continually take pictures as I work through all stages of the process. Along with this, I hope to have a finished project that can be presentable. If flyable, I may also produce a video with footage of it flying.

3. By designing/constructing a small scale aircraft, I am ultimately putting to practice everything I have been researching. It is a much more hands on approach that will test my knowledge on the matters and force me to learn much more. This is basically a much simplified, basic and doable aerospace engineering activity. My first interviewee also suggested that I look in to RC craft to help me learn more in depth on aerodynamics, so I am sure it will provide me with a lot of information.

September Additional Blog Post

     This month, I have not done too much outside work revolving around my senior topic. However, I have been extensively looking into an in-development aircraft. It is known as "Synergy" and is being designed to provide a stable aircraft, comparable to a limousine of the sky, that can achieve high speeds and great fuel efficiency. It is fast and comfortable and combines many aerodynamic and other drag-reduce proven technologies to provide substantial fuel-economy.

(Synergy Aircraft)

     One of the main features this aircraft's design implements is a high span efficiency. Span efficiency is basically the distance a wing can travel vertically, before dropping horizontally. It also pertains to the aircraft's aspect ratio, which is the wingspan(b) and area of wings(s) (b^2/s). By making the wings non planar(box shape on the wings) it helps increase the span efficiency, which ultimately allows the plane to go much further and efficiently for the same wingspan as normal craft, while also being capable of higher speeds.

(Non planar wings shown above)

I plan to continue to research this aircraft as it gets further along in development and research. Currently, it has created a kickstarter program to raise funds to get it up in the air and create more prototypes. The ultimate end goal of this project is similar to my current proposed essential question,( What is the best way to alter the basic design of an aircraft to improve fuel-efficiency?) because they are altering the basic structure to increase the efficiency and provide comfort.

Blog 6 - Second Interview Preparation

1. Who is your mentor and where do they work?

     Frank Pina at the NASA Aero Institute in Palmdale has told me I can revisit the facility for mentorship whenever he is available, however I am going to continue to look for a more convenient and closer mentorship.

2. What five questions will you ask them about their background?
  • Where did you attend college? Did you pursue an aerospace degree higher than the minimum 4 year bachelor-program? 
  • What is your official position at your workplace, and how did you come about the job offer?
  • What kind of internships and aerospace work did you complete before your current position?
  • What led your decision to choose aerospace engineering over the many other specialties in engineering? 
  • What has this company done for the aerospace engineering industry? Has it left a large impact on the industry? What is it known for?

Blog 5 - Mentorship Reflection

1. Mentorship question: Describe your experience in how you found your mentorship? If you haven't found one yet, describe your experience so far in the search of a mentor.

     Well, I have basically found a mentor, but am still going to continue searching for one. I have not logged any hours outside of summer, however, so I have been searching. My experience in looking for one has kind of been awkward. One JPL engineer I had called and emailed talked to me up to the point where he wanted my academic resume, I sent it and never heard from him again. This kind of thing has happened a few times and is kind of frustrating, but understandable. My mom has been a big help in this because she has made so many contacts over the years. Her friend's have put me into contact with the NASA site I did my summer mentorship at and have given me a few leads as of late.

2. Research question: What has been your most important article you have read so far and why?

I think the most important article I read so far was one titled "Atmospheric Flight" straight from the NASA website. This article basically introduced me to the basics of airplane and airplane design. It gave me the information I needed to root my essential question in fuel conservation because it introduced me to the concepts of drag, and how it effects an aircraft. My core understanding of lift and how wings make planes flyable also came mostly from reading this article all the way through. Ultimately, it just gave the basic information I needed to understand aerospace engineering a little deeper.

August Additional Blog Post

     During my mentorship, one of the things I got to do was work with a coding program/language known as LabView. It is a type of visual programming language that can make coding easier for some, especially when there is a lot of statements calling on previously stated things. It is basically code put into a diagram like below:


     What I was asked to do with this language was more or less a repair job on a nearly completed program. One of the engineers there had begun to develop a program that would take in information from these new fiber-optic sensors that had been placed on a building model. The model appeared much like this:


     However, it was all metal and strapped with a line of sensors going down each metal bar. The end goal of the program was to display the information from the sensors into a graph. This graph would move as the structure did. This information would then be used to test the stress of the structure, but mainly was to test how effective they were at measuring the stability of certain structures. I ended up fixing the program and getting it to display the information, with help from the original engineer who had begun to develop it. I came to understand the basics of a program that most of the engineers said they use often and prefer over common coding languages. The application of these sensors was planned for many aircraft, but being first tested on stress of structures. I was exposed to that part for a good while on an experimental aircraft that was being designed to take these sensors to auto adjust a plane for the given wind conditions.

Blog 4: Interview Preparation

1. Who do you plan to interview? Why?

      I have been unable to schedule an interview, but I should be able to interview an Aerospace Engineer who works at JPL that I have come in contact with. However, this may not workout so I am continuing to look for another interviewee. I want to interview him because he works in JPL which works directly with rockets and space components something I think my topic will focus on more.

2. What additional questions do you plan to ask?

  • How did you choose what specific area of Aerospace Engineering you wanted to pursue?
  • What can I truly expect when and if I get into this field?
  • What have you come to enjoy and appreciate about your work?
  • What can I expect in college under this major?

Blog 2: Summer Mentorship

1. Mentorship Log

2. Contact Information
Frank Pena
(661) 276-2622
francisco.pena@nasa.gov (He does not always answer his phone)

3. What questions were raised because of the 10 hours of experience?
What side of Aerospace engineering would I consider going in to?
What is the best place I can go to school for this?
Should I consider other fields of engineering?

4. What was the most important thing you gained from this experience? Why?
The most important thing I gained from this experience was the exposure to multiple different types of engineering. When I went there looking to be mentored in Aerospace engineering, I instead got to see Aerospace, Mechanical, Civil and Electrical engineers working together and specializing in different things. This was so important because it has helped me understand what engineering as a whole is and a little more about all of the possible fields I can join.

5. What is your Senior topic going to be? How did what you did help you choose a topic? Explain.
My senior topic is still going to be Aerospace engineering, space and things that fly have always amazed me and my experience helped show me why. This mentorship helped me choose my topic because it solidified my interest in aerospace engineering with first-hand experience, as well as it exposed me to other possible engineering topics and things I considered pursuing, but no longer want to after direct experience in those topics.

Wu, WesleyStructural Engineering

What questions do you have that haven't been answered about the senior project?

I do not really have to many questions at the moment besides knowing the exact requirements. I would also like to know how many sources and interviews are required/used throughout the whole process?

What has been the most important part about the senior project based on what you are seeing in the 2-hour presentations?

From what I have seen, the most important part of the senior project is actually learning and understanding things from your topic. Most of this, as I saw, came from actually doing the mentorship consistently and taking it seriously. Then you use all of the knowledge acquired to come up with the 3 answers to your essential question.

What topic are you considering doing and why?

I am considering doing something in the engineering field, specifically aeronautical or aerospace engineering. I consider engineering to be something I am highly interested in right now and as a future career. I really enjoy math and have taken calculus and such to help me get there, and I think doing it as a senior project will really help me understand it on a much greater level. The aeronautical and aerospace part stem from the fact that I think space and engineering are cool and it puts them both together, as well as missiles and airplanes. 

What are you doing for your summer mentorship?

Currently, I am in the process of getting one at NASA's JPL. My mother has friends who are aerospace engineers there and have gotten me in touch with the internship advisers and other people at this place. If this does not go through, I will possibly get in touch with someone at my parent's work who is an engineer.
